HOLO-KROME 09055 مسامير كتف بمقبس 16mm X 100mm | رأس مقبس | محرك مقبس | فولاذ سبائكي أكسيد أسود حراري (10/عبوة)

Used these as pivot points for a custom jig I built and the hex drive made installation quick with a standard Allen key. The black oxide finish looks sharp and hasn't shown any wear after a few weeks of heavy use.

The precision ground shoulder on these screws is absolutely flawless for shaft alignment. My project needed a smooth bearing surface and these fit the bill perfectly, with the hex socket drive making installation a breeze.

Used one as a pivot for a homemade jig and the shoulder rode smooth with no wobble. The black oxide finish hasn't chipped even after tightening them down with an Allen wrench. Solid buy for the price.
